Mr.Do's Nightmare (hack by Krazy Ivan) — About this game
Mr. Do’s Nightmare replaces the familiar digging structure with an overhead action field. The character moves through the stage without tunnelling, while separate bonus stages interrupt the main action. The result is presented as a distinct game design built around the familiar clown rather than another version of the original dirt-clearing maze.
